KCL: Ionic Bonds
KCL is an ionic bond. This is because potassium (K) has a charge of +1 and chorine having a charge of -1. K gives one electron to chlorine, this makes it so both of them have a full valence shell. GeCl4 is a covalent bond, due to it being hard to separate its 4 valence electrons so Germanium shares its 4 valance electrons to Chlorine therefore making 5 full outer valence shells. BrCl is a covalent bond. Chlorine has a high electronegativity then bromine, and is a dipole-dipole which indicates to why it has a low melting point. Lastly CrCl3 is an ionic bond. Elements have melting points and how metallic an element is determines the melting point. When the element is metallic the melting point is very high and when it becomes more gaseous the …show more content…
KCl and CrCl3 has a high melting point because the bond is strong and requires a lot of energy to break. Covalent bonds such as GeCl4 and BrCl have very low melting points due to the opposite reasons, it has a very weak structure and requires less energy to break the bond. This is represented on the table with KCl having a melting point of 770*C then CrCl3 with 1150*C Then GeCl4 with -50*C and BrCl with -66*C respectively. Ionization energy (IE) increases from the bottom left side to the top right side of the periodic table, due to the stability of the elements and how far away the electrons are from the nucleus which determines how easily it can be transferred or taken away. Potassium has a low IE because its final shell has 1 valence electron, meaning it requires very little energy to remove that electron. Chromium, Germanium and Bromine all have increases of ionization energy respectively making it harder and requiring more energy to remove an electron from the outer shell. Therefore also making the atom stability

415 Words | 2 PagesCovalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons
Explain Why Nacl Is Sodium Dichloride
257 Words | 2 PagesCovalent bonds are strong due to the hybrid formation of orbitals it has. Just like diamond it shows how strong a covalent bond between carbon can be. There are also Polar Covalent which are between covalent and ionic. They share electrons but spend most of their time around the atom versus the

Gallium Research Paper
147 Words | 1 PagesThe melting point of Gallium is 29.76 °C (302.91 K) with a boiling point of 2200 °C (2473 K). It has the second largest liquid range of any element and is one of the few metals that is liquid near room temperature and it can melt in your hand. Liquid clings to glass or wets it and similar surfaces. Gallium also has the unusual property that it expands when it freezes. Gallium has 31 Protons and Electrons and 40 Neutrons (in its most abundant
Comparison Of Sodium And Valence Electrons
503 Words | 3 PagesFluorine has higher ionization energy than boron because fluorine’s valence electrons experience greater attraction to the nucleus. Both boron and fluorine share the same highest principal quantum number, but since fluorine has an effective nuclear charge of 2.2 and boron has an effective nuclear charge of 1.4 it will be harder to remove a valence electron from fluorine. 2c. Oxygen has lower ionization energy than nitrogen because it’s valence electrons are less attracted to the nucleus than those of nitrogen. Both nitrogen and oxygen have valence electrons at n=2, but since oxygen has a lower effective nuclear charge than that of nitrogen it will be easier to remove a valence electron, therefore requiring less energy to ionize

1039 Words | 5 PagesAs mentioned in number 13, the data for the melting point makes sense because my pure product and given compound almost perfectly matched. 17. Again as explained in number 14, the TLC data made sense because my pure compound and 4-tert-butylbenzyl phenol had similar distances from the solvent origin of the plate. The presence of benzyl bromide and benzyl alcohol also explains how not all the product dissolved in the filtrate.

Chemical Bonds: Explain The Difference Between Ionic And Nonmetals
448 Words | 2 PagesSo metals are mostly cations and nonmetals tend to be anions. Both ionic and covalent bonds share one property that is well known in the periodic table. Electronegativity can determine the character of bonding, for example if the electronegativity is below

Chlorin And Sodium Similarities
553 Words | 3 PagesCompared with ionic bond, they share several similarities. On one hand, these two bonds are strong interactions between particles which like glue to connect atoms. In other words, it’s hard to break the bonds between the elements. The energy needed to break 1 mole O2 is about 500 KJ and to break 1 mole NaCl, it’s around 768 KJ. On the other hand, particles tending to be stable, their valence electrons are ready to be 8 like noble gases（in very few conditions, it’s 2）.

379 Words | 2 PagesSince they gain/lose/share the same way. Free Electrons Valence shell electrons have the weakest attraction since they are the furthest to the nucleus. When the electrons are loosely bonded thy start to randomly wandering around (free electrons). This happens the movement is controlled by the electronic current. Molecular Bonding Electrons are responsible for chemical bonding.

Super Heavy Alchemy Research Paper
1299 Words | 6 PagesIt may seem counterintuitive that as atoms become heavier they may exist a group of very stable ones, but, like electrons, protons and neutrons arrange themselves in “shells” (Witze, 2010). If an element has a full shell of protons and neutrons it will be more stable than one that has only a partially filled shell (Witze, 2010). A “doubly magic” nucleus is one where both of the subatomic particles fill all their shells; the nucleus is extremely stable (Halka & Nordstrom, 2011, p. 128). This is the reason there may be an island of stability at the end of the periodic table. Some theories predict that the island of stability may occur with 120, 124, 126, 168 or 184 protons in the nucleus (Halka & Nordstrom, 2011, p. 129).
Ionic And Covalent Compounds Lab Report
902 Words | 4 PagesProperties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
Ionic Bonds
580 Words | 3 PagesIonic bonds form when a non-metal and a metal exchange electrons, while covalent bonds form when electrons are shared between two non-metals. There are two bonds known as Ionic Bonds and Covalent Bonds. Ionic bonds form between metals and non-metals whereas covalent bonds are formed when electron are shared between two non-metals. An ionic bond is formed though an electrostatic attraction between two positively charged ions. Bonds between a partly ionic ion and a partly covalent ion is known as a polar covalent bond.
